Improvement in car-couplings



UNITED STATES PATEN OFrIon ALBERT SGOLES, OF OIROLEVILLE, I OHIO.

IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 181,484, dated August22, 1876; application filed July 15,1876.

To all whom it may concern:

Be it known that I, ALBERT SooLEs, of Oircleville, in the county ofPickaway and State of Ohio, have invented a new and valuable Improvementin Oar-Couplings; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making apart of thisspecification, and to the letters and figures of refence marked thereon.

The figure of the drawing is a representation of a longitudinal verticalsectional view of my car-coupling.

This invention is an improvement on the car-coupling secured to Weldon0. Scoles by Patent No. 160,473, dated March 2, 1875, and subsequentlytransferred by assignment to Albert Scoles. It relates to devices forauto-- matically coupling cars on railroads, and is applicable todraw-bars of difierent heights, as well as to those of the same height,from the ground.

This invention dispenses with the springs used in the above-mentionedpatent, and substitutes for the inclined levers used therein a singleY-shaped lever and straight actuatingrod, hereinafter particularlydescribed.

In the accompanyingdrawings, A represents a draw-head, provided at itsinouth with arigid depending plate, B, which is perforated at I). Saiddraw-head is also provided with the usual pin-holes a a, to allow thevertical movement of a heavy coupling-pin, O. Said pin is pivotallysupported by the free end of a vertically vibrating arm or plate, D,which is hinged at its rear end 01 to the top of the drawhead, ordraw-bar, and slotted longitudinally at d. To the underside of draw-headA is hinged at e one of the upper arms, 0, of a Y- shaped lever, E. Tothe lower arm 0 of said lever is pivotally attached a horizontal rod, F,which passes through perforation b in plate B. The other upper arm 6 oflever F carries a pivoted extension-plate, G, which passes verticallythrough openings A in the draw-head A. Said extension plate islongitudinally tached to the inside of draw-head A, sets in slot 9, andguides and limits the play of the extension-plate Gr. Lug g ordinarilysupports the pin-carrying arm or plate D, a little back of slot d insaid arm or plate.

The operation of the device is as follows: The parts being set as shown,when the link to be coupled enters the draw-head A, the opposite carwillstrike the outer end of horizontal rod F, driving said rod inward,so as to make Y-shaped lever E and extensionplate G revolve about thepivotal point 6 except so far as such motion of the extensionplate iscontrolled-by pin 9 This movement lifts the pivoted arm D until lug 9passes under slot at, whenthe weight of coupling-pin G will cause saidslotted arm to fall down over said supporting-lug, like a sleeve, andsaid coupling-pin will fall through holes a a, behind the entcring-link,effectually coupling the cars. I

This coupling is applicable to draw-heads which are at differentheightsfrom the ground, as well as to those that are at the same height.But in the former case it is necessary to use a bent link, the ends ofwhich are adapted to enter the different draw-heads.

What I claim as new, and desire to secure I by Letters Patent, is-

1'. The combination of pivoted slotted arm D, with pin O, Y-shaped leverE, horizontal rod F, and extension G, substantially as set forth.

2. The combination of drawhead A, perforated plate B, horizontal rod F,lever E, slotted extension G, pin g, lug g slotted arm D, andgravitating-pin O, substantially as and for the purpose set forth..

In testimony that lclaim the above I have hereunto subscribed my name inthe presence of two witnesses.

. ALBERT SOOLES.
